APPARATUS FOR APPLYING SHEATHING TO THE HULLS 0F VESSELS, tro- SPECIFICATION forming part of Letters Patent No. 445,502, dated January 27, 1891.

Application filed August 29, 1889. Serial No. 322,370. (No model.)

T0 at whom, it may concern.-

Be it known that I, FRANKLIN EWING, Jr., of Atlantic Highlands, in the county of Monmouth and State of New Jersey,haveinvent- (-d a new andImprov ed Ship-Builders Helper, of which the following is a full,clear, and exact description.

The object of my invention is to provide an apparatus designedfor use in applyi ngsheathing to the bulls of boats and vessels; and to this end my invention consists, principally, of an apparatus comprising clamping plates or 'jaws for securing the apparatus to the beam,

at lifting-screw, and an arm carrying a pressure-screw at right angles to the liftin -screw.

The invention also consists of the construction, arrangement, and combination of parts, all as hereinafter described and claimed. Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 illustrates one application and use of my invention. View, and Fig. 3 is a plan view.

A represents the body of the apparatus. To one end of this is secured one of the clamp plates or jaws B. The opposite end is by preference reduced in size, as shown at a, and upon it is placed the sliding clamp or jaw O. The jaws B O are formed with opposite screw-threaded passages 19 b to receive the right and left hand screw-bolt E, which on being turned to the right. will close the jaws upon a beam W or other object to which the apparatus may be applied, and to effect a firm grasp the inner surfaces of the jaws are formed or provided with one or more spurs c c, as shown clearly in Fig. 3.

In the center of the body-piece A is formed a screw-tap (Z, in which works the liftingscrew F. This is by preference provided with a swiveled plate f, which is adapted to engage with the edge of the board W for lifting it, as indicated in Fig. enabling the Fig. 2 is an enlarged front screw to be turned without chafing the board, and the lower or outer end of the bolt is by preference formed with the prongs or forkf f, between which a lever may be placed for turning the screw with more or less power, as circumstances require.

To the outer end of the clamp plate or jaw B is secured the arm G, formed at its upper end with an internally-screw-threaded wrist g, in which Works the pressure screw-rod H, for pressing the board W up to the beams WV of the boat or vessel. The inner end of this rod H is provided with a swiveled plate H, as shown clearly in the drawings, and the outer end is provided with a lever H for turning the rod H. The arm G is by preference held to the clamp-plate B by a set-screw g, so that by loosening the screw the said arm and pressure-screw may be removed and replaced at pleasure and adjusted along the jaw to different positions, as circumstances require.

The end of the screw E may be provided with forks e, if desired, to receive a lever for turning the screwto close the jaws with great force upon the beam.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The apparatus herein shown and described, comprising a b0dy-piece carrying a liftingserew, two jaws applied to the bodypiece, a right-and-left-handscrew for operating them, an arm applied to one of the jaws, and a pressure-screw held by said arm, substantially as described.

2. The body-piece A, carrying the liftingscrew F, in combination with the jaws B 0, applied to the ends of the body-piece, and the right-and-left-hand screw for operating the jaws, substantially as described.
